Step-sister entered my room and caught me masturbating to some explicit content. Initially, she laughed it off but then reminded her of the times our parents used to engage in sexual activities and how we would often follow their lead by having sex regularly. This was when she decided to help me out with my situation. She started by performing an impressive deep throat job, swallowing my entire cock whole and shoving it far down her throat - a skill I had sorely missed. After that, I plunged my erection into her warm, inviting pussy and pounded away all over the room.
